Selecting elements of a Python dictionary greater than a certain value

.items() will return (key, value) pairs that you can use to reconstruct a filtered dict using a list comprehension that is feed into the dict() constructor, that will accept an iterable of (key, value) tuples aka. our list comprehension:

>>> d = dict(a=1, b=10, c=30, d=2)
>>> d
{'a': 1, 'c': 30, 'b': 10, 'd': 2}
>>> d = dict((k, v) for k, v in d.items() if v >= 10)
>>> d
{'c': 30, 'b': 10}

If you don’t care about running your code on python older than version 2.7, see @opatut answer using “dict comprehensions”:

{k:v for (k,v) in dict.items() if v > something}
